Mr. Chartier Page 1 September 20, 2011 shorelines should be irregularly shaped to promote a diverse wildlife habitat. The Colorado Division of Wildlife (DOW) must be consulted where wildlife use is the proposed future land use. (e) Specify the reclamation treatment of any waste rock dumps, tailing impoundments, underground mine openings, ditches, sediment control facilities, buildings and other features specified in your mine plan but not previously addressed in the Reclamation Plan narrative. These features must be shown on Exhibit E - Map. This should describe the measures taken to minimize disturbance to the hydrologic balance, prevent off -site damage, and provide for a stable configuration consistent with the proposed future land use. (f) All Limited Impact 110 applications must provide an estimate of the actual costs to reclaim the site based on what it would cost the state using an independent contractor to complete reclamation. Include the unit costs for the following activities as appropriate to the operation: backfilling, grading, topsoil application, seeding, mulching, fertilization, and labor to complete reclamation. Determine and specify the point during the operation when the site has reached a point of maximum disturbance. The cost to reclaim the site to the specifications of the Reclamation Plan at this point must be estimated. Unit costs (cost per cubic yard), volumes, haul or push distances, and grades must be included when backfilling and grading is part of the Reclamation Plan. Volume and unit costs for finish grading, subsoil and topsoil application must be provided in terms of cost per cubic yard. The estimated cost for fertilizer, seed and mulch acquisition and application must be provided as cost per acre. (i) Equipment costs must include such factors as equipment operator wages and benefits, fuel and lubricant consumption and depreciation. The cost to mobilize and demobilize the equipment from the nearest population center should be estimated. (ii) All items referenced in the Reclamation Plan must be included in the cost calculation. These items in addition to earthwork, such as detoxification, building demolition, fencing, monitoring well sealing or stream channel reconstruction must also be included in the reclamation cost estimate. (iii) After the direct costs noted above have been estimated, the Office may add up to an additional maximum eighteen and one -half (18.5 %) percent of that total, which includes private contract, typical overhead costs. This additional cost is required to cover indirect costs that an independent contractor would incur when performing reclamation of the site. Five (5 %) percent additional cost shall be added to cover Office administration cost in the event of bond forfeiture and permit revocation.
